Is there a "legit" KN95 on Amazon Prime? : Masks4All
I tried all three and I can tell the KN95 has a better seal than the surgical masks and they are designed to filter out 95% of particles, but because the seal isn’t as good as the N95, it probably doesn’t filter out 95%. However, KN95 is definitely better protection than a surgical mask. I can’t comment on the Amazon prime.
